The function of ENSG00000123297 (TSFM, Ts translation elongation factor, mitochondrial) is as follows. Associates with the EF-Tu.GDP complex and induces the exchange of GDP to GTP. It remains bound to the aminoacyl-tRNA.EF- Tu.GTP complex up to the GTP hydrolysis stage on the ribosome. Participates in mitochondrial translation (PubMed:27677415). .
